Corrosion and Structural studies of Galvanostatically Electrodeposited ZnMgO Thin Films

Shraddha Bais, R. K. Pathak

Abstract: ZnMgO thin films have been grown on Stainless steel substrate by galvanostatic electrodeposition from nitrate baths. The effect of bath composition was observed. A comparative study of corrosion parameters were done in three different electrolytes, NaCl, HCl, H2SO4 by tafel plot.1-Phenyl-1H-tetrazole-5-thiol was used as inhibitor in deposition bath and its effect on corrosion rate was determined and found effective in corrosion inhibition of ZnMgO thin films. The morphology and structural characterization of thin films were done by Scanning Electron Microscopy (SEM) and X-Ray Diffraction pattern (XRD). Elemental composition has been determined by Energy Dispersive X-Ray spectroscopy (EDAX). XRD confirmed that the films possessed Hexagonal wurtzite structure. Structural changes were also observed by XRD studies which indicate a possibility of partial replacement of Zn atoms by Mg atoms in the lattice structure.
